16 ohm speakers: Pros & cons
Share on Facebook The ohm rating of a loudspeaker is its dynamic impedance with dynamic acoustic program. This value runs higher than electrical resistance when conducting DC current from a volt-ohm meter. It is only one rating among other factors that allows users to classify speakers so they can be matched to amplifiers. The question, “How do I change 4 ohm speakers to 8 ohm? Speaker Impedance Originally, most speakers were 16 ohms because this worked best with tube amplifiers. Later, speaker drivers with about 8 ohms were the right match for transistor amplifiers because they provided the best balance of output power, volume, fidelity and low distortion. Early automotive stereos necessitated speaker drivers with the much lower 4 ohm impedance to get the needed volume, albeit with some loss of sound quality because the driving voltage was limited to volt DC automotive battery-alternator electrical systems. Modern automotive amplifiers are able to internally jack their output voltage as evidenced by those annoying thumpers prowling the streets. An amplifier has to apply twice the voltage to an 8 ohm speaker to get it to allow the same amperage and thus watts as a 4 ohm speaker. Inversely, an amplifier intended for 8 ohm loads might pass too much current if used at moderate to high levels with 4 ohm speakers, which would melt its output transistors.
4 ohm Speaker to a 2 Ohm amp
Why do you think tube amps have multiple sets of taps? By keeping the speakers connected to the taps that most closely approximate your speakers load, you will get the most efficient transfer of power at full bandwidth. As bobrex has said, it’s a moving target because speakers have complex impedance curves, not a simple and static impedance. So speaker makers will rate their speakers nominal impedance which will provide you with the closest impedance for choosing a tap.
The real fun part comes when you buy a 6 ohm speaker.
PAGE 31 PARALLEL: When wiring in parallel, the resistance of the speakers decreases. Two 8 ohm speakers wired in (hooked-up) Parallel results in a 4 ohm load. It’s easy to calculate the effect of a resistive load when all the speakers are all the same resistance.
I had one of those when they were new, with a V2 cab because the Stones did I was working clubs then and it was just too loud for the rooms. Yeah, I’ve heard they are really loud amps. I bought it broken, brought it to a tech, and it’s ready to be picked up. I haven’t played it yet, or any V4 for that matter, I bought it on it’s reputation for great clean sounds and from what I’ve heard on youtube demos.. I noticed that the Stones used the 7 knob models mine is a 6 knob.
I wonder if they were using the Distortion model or the Master Volume model.. Is it so loud that it’s hard to tame even at the lowest volume settings? You said that the Altair attenuator messed with the amp’s tone. Did you ever try the Master Volume footswitch that was made for the V4? Anyways, back to the 4×12 wiring.. If I install the two jack switch panel, and wire two speakers per side in parallel to each jack, will the switch do anything?
Would it be like have two 2x12s in the same cab no matter what position the switch is set.. Also, like I mentioned in my original post, is there a diagram out there that would allow me to wire the speakers to the switch panel so I can choose between running the cab in Mono at either 4 or 16ohms?
Silly question do I need 4 OHM pa speakers for an amp that is 4 OHMs
Power amplifiers are devices that amplify electrical signals that have been adjusted to an appropriate volume and tone sent from the mixer, to a level that can be converted to acoustic sounds by the speakers. There are various types and models of power amplifier, varying in size, shape and output power, which are suited to different situations. Types of power amplifier There are three major types of power amplifier, the characteristics of which are described below.
Stand-alone power amplifiers amplify the signals sent from mixers to make the speakers produce sound. Several stand-alone power amplifiers can be installed together in racks, making it comparatively easy to build a large-scale PA system. Since the mixer and power amplifier which require a power supply are integrated into the PA system, only one power supply connection is required, and there are less connections to make than with stand-alone amplifiers.

I would not connect a 4 ohm and 6 ohm speaker in parallel.
how to hook up 2 pairs of speakers to 2
Will 4 ohm speakers work ok with an 8 ohm amplifier? Yes, you can use 2 in series, IE daisy chain them to add up to 8 ohms. For stereo you would need 4 speakers not 2. Most Amplifiers work OK driving to a lower impedance loads anyway so just hook them up. Very high power levels may overheat the amp but at normal volume… it should be fine..

You don’t want to know El Hombre Lobo said: I can’t tell if the sub is a single voice coil or dual. Perhaps someone can correct me? In any case, could I not boost the gain on the amp to get more then W? For this JL sub in particular the company says W is optimal while W is the bare minimum. If I could increase the amp gain to the W area I would be happy. Is this possible or is the amp limited to a ceiling of W when connected to an 8ohm sub? If there was a way to up the power, it would start to distort.
The problem with distortion is the peaks of the signal start to flat top clip. The problem with this is the clips are a steady DC voltage. The voice coil dissipates heat because the signal is constantly varying. When its starts to clip it average power being delivered to the voice coil goes way up and can burn it up.

That is two 4 ohm speakers in series will give a total load impedance of 8 ohms. Therefore you could have two speakers on each side of the amplifier (right and left). This will get more power to each speaker than running through a speaker selector switch.
How do I connect a set of four ohm speakers safely to an eight ohm system? There are many variables to consider when connecting 4 ohm speakers to your system. Please consider the following: Define your system Are you using a Receiver or separate power amp to drive your speakers? Most midfi Receivers may have problems adequately driving a 4 ohm load. However, many of the better Receivers today have a large enough power supply, heat sink area, and current capability in the amp sections to handle 4 ohm loads.
You are usually safe running these speakers on the Flagship Receiver models from: Some Receivers have an impedance selector switch. In most cases we recommend the 8-ohm or more setting.
Can I hook up 8
That is, in the one amplifier box, there are two different amplifiers. For the purposes of this article, we are talking about connecting multiple speakers to a single amplifier only, that is, either the left or the right, or any single amplifier. Of course you can connect multiple speakers to both the left and right amp of a stereo — you just need to follow the principles twice, once for each amp. Multiple Speakers on One Amplifier By adding an extra speaker to the output of an amplifier, you are adding to the load of the amplifier.
That is, two speakers is double the load of one speaker. Most amplifiers can cope with a load of two speakers.
Two 8 ohm speakers wired in parallel will have a net impedance of (8 divided by 2) 4 ohms. If you have three speakers, each at 8ohms, divide 8 by three to get a total impedance of ohms. If the speakers do not have a common impedance, you can use formula 1 for .
This confusion is also a likely cause of many blown power amplifiers. This article is intended to explain the meaning of speaker impedance and guide the reader in connecting multiple speakers to an amplifier. This article is NOT intended for engineers, technicians, or even serious students of electronics technology. What are ohms, anyway?
The ohm is the unit of measure for impedance, which is the property of a speaker that restricts the flow of electrical current through it. Typical speakers have impedance ratings of 4 ohms, 8 ohms or 16 ohms. For the average audio user, the nominal impedance is the dominant characteristic and for the purposes of this discussion, we will use the nominal value of the speaker’s impedance. Why are ohms important? Too many speakers on a solid state amp can burn up the power output section.
How to hook up speakers correctly for proper impedance
I am hoping for a relatively simple answer to the below question: Am I about to blow up my amp? It’s rated for watts per channel minimum RMS power with 8 ohm loads, both channels driven. The speakers are listed as 3 ohm impedance and appear identical. They each have four 2″ woofers and one 1″ balance dome tweeter. The amp from that system was rated at 75 watts minimum RMS, per channel with 3 ohm loads with both channels driven, from , Hz.
or speaker box. The impedance of a speaker is normally 4 ohms, 6 ohms or 8 ohms. If it isn’t written on the back of the speaker, check any paper work that might have come with the speaker, or look up the specifications on the web.
Loading, Phase and other tips. Wiring them up to provide the most effective load and making sure that all of them are in phase will help you sound as good as possible. Its not really hard to do, as long as you understand a few things about loading and how to connect your speakers to provide an optimal resistive load. I’m starting with the assumption that you will probably be building some of your own speaker cabinets and will need to know how to wire up the speakers properly.
Luckily, the rules are the same for cabinets that are wired into your system. All speakers and speaker cabinets have some resistive ‘load’, measured in ohms. When you bought your PA system, or other Audio amplifier, somewhere in the documentation, or possibly stamped on the back of the gear, is something that indicates the ‘load’ that the system is designed for. In many cases, the Power Amplifier stage will state that a ‘load’ of 2, 4, 8 or 16 ohms is what you should be using for the Speaker system.
If you don’t know what you gear is rated for, most audio systems are designed to safely operate with an 8 ohm load; many can operate at 4 ohms. You are safe running everything at 8 ohms; never run below 4 ohms unless you are absolutely certain that your system will handle it properly. If you have a Power amplifier that is Solid State Transistors or FET’s , you should never apply a dead short to the Speaker load – it may destroy the output stage almost immediately.
If you are using a Tube amplifier with an Output transformer – you should never have an open circuit at the speaker load; this can damage the Output transformer Very Very Expensive!! Some Stereo Solid State Power amplifiers get very grumpy if you don’t provide a load for both channels – if one channel has a load and the other doesn’t; you could burn out the entire power amplifier I have a Phase Linear Power Amp under my desk that would make a great boat anchor as a result of this discovery You need to keep in mind that the lower the resistance of the load, the more difficult it is for an amplifier to drive the load without distortion.
4ohm amp to 8ohm sub
How to hook a 4-ohm speaker to an 8-ohm stereo Category: However, impedance fluctuates based on frequency, meaning that extremely low bass or high treble can dip into the 2-ohm range or below for brief periods. Most mixers of recent vintage will have this type of connection, but if yours does not, there is still a way to do it. PC speaker systems, for example, are usually packaged with one or two subwoofer bass speakers and a series of smaller surro [More] Category:
Apr 26, · This video explains how speaker impedance matters, especially when connecting multiple speakers to your HiFi amp. It also demonstrates how speaker .
Using a higher ohm rating is not going to hurt anything. It is based on the AC resistance of the speaker at a frequency of Hz. A tone at Hz is sent through the coils, and special resistance measuring equipment determines the resistance of the coil in the speaker. That resistance is going to vary as the frequncy of the music changes. That speaker resistance is known as a “dynamic” resistance for a reason.
That reason is what I just described. Be very careful how you wire that speaker up to your amplifier.
Single Voice Coil Vs. Dual Voice Coil Subwoofers
How Many Speakers can I put on an 8 ohm amp? April 14th, by Roemtech The question arises: How many speakers can be put on an 8 ohm amp? The answer is, as many as you want, theoretically speaking. You purchase eight of the finest ceiling speakers you can find otherwise known as the SP N. You hire a tech to put them in and taking the easy way out, he wires them in parallel.
So the ‘old’ amp I am replacing and the ‘new’ amp have A & B speaker inputs and up until right now, all 4 speakers have been traditionally wired (+ & – on each speaker to red & black on amp).
Demystifying speaker impedance–what audio shoppers need to know The Audiophiliac clears the air about the mysterious subject of speaker impedance. This letter sums up the typical quandary: I’ve done a lot of research and found that owning a 6 ohm receiver limits the selection of brands that I could look at in store or online. Rotel I’m all for the speaker upgrade, but he went off track with the concern about his “6 ohm” receiver. The writer mistakenly thinks he’s limited to buying 6 ohm rated speakers.
Any 8-ohm rated speakers would work just as well, and since the vast majority of speakers are 8 ohm rated, his choice of speakers is wide open. Back to the question at hand: It’s never a fixed number, a 6 ohm speaker may be, on average 6 ohms, but its actual impedance varies with the frequency the speaker is reproducing at any given instant. For example, it may be 4 ohms at 50 Hertz, shooting up to 21 ohms at Hz, dropping back to 7 ohms at 1, Hz, and up again to 9 ohms at 10, Hz.
So in other words, it’s impossible to “match” a speaker to a receiver. Impedance is a moving target.
